\"Patch-Set <\/p>\n

Am 2. Juni stellte Erik Biggers (Ingenieur bei Google) neue Implementierungen von AES-XTS vor, die eine deutlich h\u00f6here Leistung der Intel\/AMD-Prozessoren mit neuen Befehlss\u00e4tzen AES-NI + AVX, VAES + AVX2, VAES + AVX10\/256 und VAES + AVX10\/512 erm\u00f6glichen.<\/p>\n

Der AES-NI GCM-Code ersetzt den vorher von Intel geschriebenen und behebt bestehende, identifizierte Probleme:<\/p>\n

\n

Dieses Update-Paket f\u00fcgt VAES und AVX512\/AVX10 die Implementierung von AES-GCM (Galois\/Counter-Modus) hinzu, was die Leistung von AES-GCM um bis zu 162 % steigert. Dar\u00fcber hinaus ersetzt es \u00e4lteren AES-NI GCM-Code von Intel durch neuen Code, der etwas schneller ist und eine Reihe von Problemen behebt, einschlie\u00dflich der enormen Gr\u00f6\u00dfe der Bin\u00e4rdatei, die 250 KB \u00fcberschreitet. Einzelheiten finden Sie in den Korrekturen.<\/p>\n<\/blockquote>\n

\n

Der endg\u00fcltige Zustand des x86_64 AES-GCM Assembler-Codes besteht darin, dass wir zwei Assembler-Dateien erhalten: Eine generiert AES-NI-Code mit oder ohne AVX, und die andere generiert VAES-Code mit AVX512\/AVX10 mit 256-Bit oder 512-Bit Vektoren. Es fehlt die Unterst\u00fctzung f\u00fcr einzelnes VAES (ohne AVX512\/AVX10). Dies unterscheidet sich geringf\u00fcgig von dem, was ich mit AES-XTS gemacht habe, bei dem eine Datei AVX- und AVX512\/AVX10-Code generiert, einschlie\u00dflich Code, der nur VAES verwendet (ohne AVX512\/AVX10), w\u00e4hrend die andere Datei nur Code generiert, der sich von AVX unterscheidet. Derzeit scheint dies jedoch die richtige Wahl f\u00fcr jeden speziellen Algorithmus zu sein, da die Einschr\u00e4nkung auf 16 SIMD-Register und 128-Bit-Vektoren zu erheblich unterschiedlichen Konstruktionsl\u00f6sungen in AES-GCM gef\u00fchrt hat, jedoch nicht so sehr bei AES-XTS. Prozessoren, die nur mit VAES geliefert werden, scheinen ebenfalls ein vor\u00fcbergehendes Ph\u00e4nomen zu sein, weshalb wir m\u00f6glicherweise nicht zu sehr bem\u00fchen sollten, diese Kombination zu unterst\u00fctzen.<\/p>\n<\/blockquote>\n
